Here's a good test of your English. How much of this new ad for Hefty Cups do you understand?

In fact, the ad is one a series of three (see the others here and here) in which wholesome-looking American moms talk about parties they've attended using slang and cultural references which would be more suited to their teenage children. Oh, and for once, you won't be getting a transcript!
